NEW YORK, April 21, 2026, 12:01 EDT
- Apple’s CEO succession, a Federal Reserve confirmation hearing, and uncertainty over U.S.-Iran relations took the air out of U.S. stocks, which slipped into the red.
- UnitedHealth’s numbers helped stem losses. Apple slipped, with John Ternus tapped to take over for Tim Cook.
- Oil remained in the spotlight with the U.S.-Iran ceasefire agreement set to expire Wednesday.
Stocks in the U.S. lost ground on Tuesday, with investors reacting to news of Tim Cook’s upcoming departure from Apple, Kevin Warsh’s Fed chair confirmation hearing, and ongoing U.S.-Iran ceasefire uncertainty. That was enough to erase the early boost from upbeat earnings reports. According to Yahoo Finance’s market file, all three major indexes—the Dow, S&P 500, and Nasdaq—slipped into the red. The AP noted the S&P 500 was trading just below its record highs late in the morning.
This shift lands just as Wall Street clings to record territory, with oil, rates, and Q1 earnings all shifting at the same time. If diplomacy with Iran collapses, crude might stay elevated—stoking inflation, clouding the Fed’s next moves, and keeping investors guessing.
The economy hardly looked sluggish. March retail and food-services sales climbed 1.7% from February to $752.1 billion, according to the U.S. Census Bureau. One thing: those numbers aren’t adjusted for inflation—a key detail with fuel prices ticking up.
Shares of UnitedHealth gave the wider market a lift, with the insurer bumping up its annual profit outlook and topping analysts’ expectations on both profit and revenue this quarter. “Margins are improving,” said Brian Mulberry, chief market strategist at Zacks Investment Management, in comments to Reuters. He pointed out that earnings could get a further boost from restructuring efforts and AI adoption. Reuters
Apple weighed on the index after announcing a shakeup at the top: Tim Cook is moving to executive chairman, and John Ternus, head of hardware engineering, will step in as CEO on September 1. Leadership swaps like this don’t come often for a giant like Apple. Shares slipped during late-morning trading.
Shares of Amazon edged lower after the company and Anthropic deepened their AI infrastructure partnership. Anthropic pledged over $100 billion across a decade to AWS technologies. Amazon, for its part, is putting $5 billion into Anthropic immediately, with the potential to raise that to $20 billion down the line. The move aims to keep Amazon competitive against Microsoft and Google in the crowded cloud-AI field.
Oil remained a key focus for traders. Brent crude hovered in the mid-$90s range, AP noted, as the market watched for Wednesday’s U.S.-Iran ceasefire deal expiration. Prices had earlier spiked to $119 during the conflict amid anxiety over the Strait of Hormuz.
This is the key worry for investors right now. Should negotiations collapse or the strait remain closed longer, oil prices likely spike, squeezing consumers and businesses with higher fuel bills. On the other hand, if a deal gets done, some of that upward pressure could evaporate quickly—putting the spotlight back on earnings reports and interest rates for direction.
Warsh’s hearing injected another element of policy uncertainty. According to Reuters, Trump’s pick advocated for “regime change” at the Fed and pitched a fresh approach to inflation, yet still insisted “monetary policy independence is essential.” The central bank’s decisions on short-term interest rates ripple across mortgages, credit cards, business lending, and bond markets.

Timing came under the microscope during the hearing. Republican Senator Thom Tillis told Reuters that Warsh’s confirmation wouldn’t move forward until the Justice Department ends its investigation into current Fed Chair Jerome Powell, a move that could muddy the transition at the central bank.
Right now, panic isn’t what’s showing up in the market. Instead, there are just too many exposed nerves. “It’s become cliched to say that the economic hit will depend on the duration of the Middle East conflict, but that cliché does ring true,” Brian Jacobsen, chief economic strategist at Annex Wealth Management, told AP.
